The formation of a solution is an example of a spontaneous process, which is a process that occurs under specified conditions without energy from some external source.

What makes a process spontaneous?
In thermodynamics, a spontaneous process is a process which occurs without any external input to the system. A more technical definition is the time-evolution of a system in which it releases free energy and it moves to a lower, more thermodynamically stable energy state (closer to thermodynamic equilibrium).

What does it mean for a solution to be spontaneous?
Spontaneity. Spontaneity & Entropy. Spontaneity. A spontaneous process is one that, once started, continues on its own without input of energy.

What makes a process spontaneous chemistry?
Spontaneous processes are reactions which proceed without requiring an input of energy because the products are at a lower, more stable energy state than the reactants. Spontaneous processes often require activation energy, but do not require a prolonged input of energy.

What makes a process spontaneous or Nonspontaneous?
A spontaneous process is one that occurs naturally under certain conditions. A nonspontaneous process, on the other hand, will not take place unless it is “driven” by the continual input of energy from an external source.

What determines if a reaction is spontaneous?
A spontaneous reaction is one that releases free energy, and so the sign of ΔG must be negative. Since both ΔH and ΔS can be either positive or negative, depending on the characteristics of the particular reaction, there are four different possible combinations.

What does it mean for an equation to be spontaneous?
A spontaneous reaction may involve an increase or decrease in enthalpy, it may involve an increase or decrease in entropy, but it will always involve a decrease in free energy that is a negative ΔG. When ΔG is negative, the reaction would go in the direction of reactants forming products.

What does it mean for a reaction to happen spontaneously?
A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring. A roaring bonfire is an example of a spontaneous reaction, since it is exothermic (there is a decrease in the energy of the system as energy is released to the surroundings as heat).

What does spontaneous mean in science?
A spontaneous process is one that occurs on its own, without any energy input from the outside. For example, a ball will roll down an incline; water will flow downhill; ice will melt into water; radioisotopes will decay, and the iron will rust.

Does spontaneous mean feasible?
For a reaction to be feasible at a given temperature, it must happen spontaneously, which means no extra energy needs to be put in for the reaction to occur. To find out whether a reaction is feasible, you can calculate the Gibbs free energy change (ΔG) for that particular reaction.
